behind another,- including means whereby the path of travel of one vehiclemay be vautomatically controlled from the next ion ward vehicle- I My invention is particularly designed for coupling a plurality of wagons, binders, etc, behind a'traction engine so as to cause the attached vehicles or machines to travel in .ofi'set positions behind the engine.

To this end my invention. consists in the features of construction, combination, and arrangement of parts hereinafter particularly described and claimed.

In the accompanying drawings forming Figurelis a plan view of my improved lnvention shown in use; Fig. 2 is a-section on line (ll-*EOf Fig. 1; Fig. 3 is a. section on line y g of, Fig. 1; and Fig. i is a deta'ilof a portion ofthe adjusting mechanism.

Referring tothe resent axles forming the steeringportions of successive vehicles. Detachably coupled upon the forward side of the axle, as by means is a cross bar 3. The cou- 'plings 2 are pivoted to allow vertical swing ingof the cross bar. Having central pivotal connection 4:"With the axle A is a draft pole 5 rigidly secured at its rear end to a second crossbar 3. The rear cross bar 3 may be connected to the axle of a vehicle at the rear *inthe same manner that the front cross bar is connected-to the axle A.

' In order to automatically control the travel of one steering frame from the steer ing frame in front I provide the following mechanism: Pivotally supported upon the outer and inner ends respectively of the cross bar are forwardly extending lever arms 6 and 7, said lever arms being brought together at their forward ends and pivotally connect- :ed to a bar 8. The bar 8 has adjustable connection at its forward end as by means of a pin 9 and openings drawings A and A rep:

10 with the outer end of an arm 11 pivotally supported upon the draft pole 5. A rod 12 has ball and socket support 13 upon the inner side of the axle A. and is threaded at its free end-through a nut 14 swiveled between the upper and lower plates of the arm ll. Thus in operatlon as the steering frame of one vehicle is turned, turning with it the attached cross bar 3, the steering frame of the next vehicle in the rear will be similarly turned in an opposite direction through the medium of the-connecting lever mechanism. As indicated in the drawings the mechanism may be so adjusted that one vehicle will travel directly behind the other and the connecting mechanism simply come into play in turning corners. The mechanism may be adjusted by means of the pin and opening connection 10, or the adjusting screw rod connection 12, or both, to so extend or shorten the connecting lever mechanism that the vehicle in the rear will-be drawn in offset position at either side of the forward vehicle desired. This becomes of particularadvantage, as in drawing a plurality of binders where it is desired to have each succeeding binder out a swath at one' side of the forward binder both in traveling across the field and in turning corners.

'VVhile I have shown my invention arranged in connection with the steering axles of such vehicles as wagons I do not restrict myself to such particular use or arrangement and may adapt the invention as an adjustable coupling wherever it is desired to draw one vehicle behind another and to automatir cally control the travel of one from the other.

I claim as my invention:

1. In combination with the steering portions of vehicles arranged in series, a draft member connecting the steering portions of successive vehicles, a lever arm'carried by the steering portion of one vehicle upon one side of said draft member, an opposed part connected with the steering portion of the next vehicle upon the opposite side of said draft member, and a bar connecting said lever arm and opposed part.

2. In combination with the steering portions of vehicles arranged in series, a draft member connecting the steering portions of successive vehicles, a lever arm carried by the steering portion of one vehicle upon one side of said draft member, an opposed part connected \vitlrthe' steering portion of the next vehicle upon the opposite side of said draft member, and a bar pivotally connected with said lever arm and adjustably connected with said opposed part.

3. In combination with the steering portions of vehicles arranged in series, a draft member connecting said steering portions, means cooperating with said draft member to hold said vehicles in relatively offset positions consisting of a bar, a support for one end of said bar carriedby the steering portion of one vehicle atone side of said draft member, and a support for the opposite end of said bar connected with the steering portion of the next vehicle upon the opposite side of said draft member.

4. In combinationwith the steering portions of vehicles arranged in series, a draft member connecting said steering portions, means cooperating with said draft member to hold said vehicles in relatively offset po-' 'sitions consisting of a bar, a support for one end of said bar carried by the steering portion of one vehicle at one side of said draft member, and an adjustable support for the opposite end of said bar connected with the steering portion of the next vehicle upon the opposite side of said draft member.

5. In combination with the steering portions of vehicles arranged in series, a draft member connecting said successive steering 'portlons, a bar extending from side to side of said draft member, a support for one end of said bar upon the rear steering portion at one side of said draft member, and an adjustable connection between the opposite end of said bar and draft member.

6. In combination with the Steering portions of vehicles arranged in series,- a draft member connecting said successivesteering portions, a bar extending from side to side of said draft member, a support for one end of said bar upon the rear steering portion .at one side of said draft'member, and'an \VM.
